Application filed September 6, 1905. Serial No. 277,212.

exact description.

The purpose of the invention is to provide an odometer of very simple,durable, and economic construction ,i wherein a series ofregistering-disks and a series of recording-disks are mounted upon thesame vcarrying-shafts, the recording-disks being so arranged that theywill show the aggregate amount of miles traveled during a number oftrips-for example, thc registering-disks being adapted'to show thenumber of miles made during each' trip, and the arrangement of thelatter disks is such that all of them may be quickly andI convenientlyturned back to zero at any time by turning the carrying-shaft andwithout changing the position of the recording-disks.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had tothe accompanying drawings, forming a part ofthis specifica; tion, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improved device. Fi 2 is a verticallongitudinal section throug the casing of the device and a artialvertical Section and side elevation of? the interior mechanism. Fig. 3is a vertical transverse section taken practically on the line 3 3 ofFig. 2. Fig. 4 is a side elevation of a recordin -disk and a section ofthe carrying-shaft, t e section being taken substantially on the line 44 of Fig. 2. Fig. 5 is a detail sectional view of a portion of one ofthe disks, a plan view of the actuating-pin' for the disk, and atransverse section through the spring-arm carrying the pin. Fig. 6 is asection taken substantially on the line 6 vof Fig. 2, the section beingthrough a spacingcollar of a registering-disk and the carryingshaft, theshifting sleeve for the disk being shown in end view. Fig. 7 is avertical transverse section taken practically on the line 7 7 of Fig. 2;and Fig. 8 is a transverse section through the actuating spring-arm `fora disk,

`ing an e arged upper end 16a.

either registering or recording, the section eing vtaken practically onthe line 8 8 of Arepresents a box-casing having suitable lugs 1() forattachment to a vehicle and a glass pane 1 1 at the top, through which aplate 12 is visible, having two series of openings 13 and 13"L therein,a series being at each side of the center of the plate, as shown in Fig.2.

vAt the central longitudinal portion of the casing A a bar 14 is locatednear the bottom of the said casing, which bar .extends from end to endof the casing and is attached thereto, being provided at its ends withupwardlyextendin arms 15 and a central arm 16, hav- A shaft Bisjournaled in the said arms 15 and 16, having endaswell as rotarymovement. The righthand end of the shaft B extends out through anopening 17 in the right-hand side of the casing, as is shown in Fig. 2,and is secured vto a knob 18, 'having a chamber 19 in its inner face, inwhich chamber' a spring 20 is located, coiled around the carrying-shaftB and having 'bearing against the right-hand arm 15 of the bar 14, as isalso shown in Fig. 2.

A series of registering-disks C is loosely mounted on the shaft B, onebelow each opening 13 and the said disks C are provided with peri heralfigures reading from 0 to 9, ine usive. Each disk C is also providedwith a central bore 21, of sufficient size to receive and turn looselyaround a sleeve 22, as is shown in Fig. 2, and the sleeves 22 of all ofthe disks are in frictional engagement with the carrying-shaft B. Eachsleeve 22 is provided with a finger 23 at its in Fig. 2,) the rear pins24 hold the sleeves 22 1 in such position that their fingers 23 arercmoved some distance from the outer side faces of the disks C, as isalso shown inKFig. 2. The disks C are spaced from each other by collars25, loosely mounted upon thev carrying-shaft B, which collars aresuliiciently large-at their inner end portions to permit the fingers 23ofthe sleeves 22 to frceiy turn therein, and a simple collar 26 spacesthe innermost disk C lfrom the central arln 16.

IOC

At the outer side face of each registeringdisk C a series of openin s 27is made, corresponding in number to t e number of figures upon theperiphery of a disk, an opening 27 being immediately below each gureupon a disk, andone side of each opening is provided With an-inclinedouter wall portion 27'?, as illustrated inFi s. 4"and 5, s aidinclination being provided or a purpose to be hereinafter set forth. I

A pin 28 is made to reject from the-outer face of each disk C aciiacentto its bore 21, the said pins being in the path of thefin ers 23 of thelsleeves 22 when the shaft Bis pus ed inward, as when said shaft iscarried inward' the outer pins 24a on the shaft will carry the sleeves22 in the same direction, so that as the shaft B is turned while at itsinner position the sleeves 22 will be turned also, `and the lingers 23of the sleeves upon strikin the pins 28 will simultaneouslyT turn all othe disks C, and said disks C are thus turned when they are to bebrought to their initial position, presenting zero at the openings 13,as will be hereinafter more particularly described.

A s rin latch-arm C is located at the inner si e o each disk C, as isshown in Figs. 2 and 7. Each spring latch-arm consists of aring-like-body 29, sufficiently large to loosely receive aspacing-collar 25, which body has a head-piece 30 integral therewithsecured to the disk to which the latch belongs and a foot-section 31,that extends to the edge of the disk, as is particularly shown in Fig.7. The foot-section 31 of a s rin -latch has a s'tud 32 extendinginwardtiiere om' or in direction ofthe opposing disk, and the studs onthe latch-arms of one disk are adapted to enter the openings 27 in anopposing disk to turn the same at a proper time, and atA the outer endof the foot-section 31 of each spring-latch arm C the foot is bent uponitself so as to extend out at an inclination in direction of an op osingdisk C, forming at the foot-section ofp each latch-arm C an inclinedoffset toe 33, as is shown in Figs. 2, 5, 7, and 8. After a disk C hasmade one revolution the foot-section of its latchwill enga e with Aaspur 34, extending u ward from t e bar 14, a spur bein provlde for eachlatch, and as the toe 33 o? the latch engages a spur 34 the foot of thelatch will be sprung outward, causing the spur on the latch to enter anopening 27 in the opposing disk to turn the same one figure, and as soonas the foot of the spring-latch has passed the spur with which itengages the sald latch, owing to its resiliency, will spring backagainst the disk,

assuming its normal position and Withdrawing the stud from engagementwith the disk which it had just moved. The bevel 27* in the walls of theopening 27 'facilitates the quick entry of the stud 32 into saidopening.

A ratchet-wheel C2 is loosely mounted upon the ri t-hand end portion ofthe carryingshaft, separated from the first registeringdisk C by acollar 35, corresponding to the collars 25, and in connection with theratchet Cz a spring latch-arm C is employed of the same construction asthose which have been described. The said spring latch-arm for theratchet-wheel is adapted to give movement at the proper time to theinitial or units disk C by reason of the stud 32 of the said latch-armentering an opening 27 in the said rst disk C, as is shown in Fi 2. Thelatcharm for the ratchet-wheel 2 is attached to .the offset36 from theperiphery of the wheel,

.the spurs 34, heretofore mentioned, being carried by the same bar 14.The ratchetwheel Cz is provided with a pawl 37, which prevents the Wheelslipping in the wrong direction, said pawl being mounted on theright-hand arm`15 of the spur-carrying bar 14.

A counter-shaft 38 is mounted in suitable bearings in the casin A belowand to one side of the bar 14, an at the right-hand end ofthe'counter-shaft 38 an eccentric 39 is secured to said shaft, as isshown best in Fig. 3, which eccentric receives a collar 40 of a dog 41,which engages with the teeth of the ratchet-wheel Cz to turn said wheelat redetermined intervals. The dog 41 may e attached to the eccentric 39in any approved manner-as, for example, the eccentric may be providedwith a peripheral groove, and a set-screw 42 may be passed through thecollar into said roove, as is shown in Fig. 3. A s ring 43 hods the dogdown to its work.

he counter-shaft 38 is rovided with a worm-wheel 44, which mes es with aworm 45 upon a shaft 46, and this shaft is led out from the casingthroughs. suitable bearing to a connection with the axle of the vehicleor other factor from which speed and power is to be taken.

It will be observed that as the ratchetwheel C2 is turned to bring thepost 32 of its latch-arm C opposite an opening 27 inthe initialregistering-disk C the said ost will enter said opening and the disk Wilturn With the ratchet-Wheel until the foot portion of the latch-arm Chas passed its spur 34., and after the rst disk C has'made onerevolution the spur of its latch-arm C will beforced by reason of thefoot of the latch-arm riding on its spur 34 into the opening 27 in thenext recording-disk to turn it in the same manner as has been describedwith reference tothefirst disk C, and this operation is re cated untilall of the disks have been turne toindicate at the openings 13 in theplate'12 the number of miles traveled-as, for example, 199 as shown inFig. l-and the latch-arms C', as shown in Fig. 2, and the first, second,and third disks C occupy. such positions relative ICD simply pushing inthe shaft to their controlling-spurs on the bar 14 that at the nextaction ofthe ratchet-wheel C2 the figure on the iirst disk will bechanged from 9 to H0, the figure on the s econd'disk from 9 to 0,. andthe figure 1 on the third disk will be changed to 2, making the readingatsuch time 200. Supposing the end of the journey to have been reachedand it is desired to ca all of the registeringdisks C back to zero, t lsis uickly done by as hasrbeen described, until the ingers'23 of thesleeves 22 are brought in the path of the ins 28 on the disks C,whereupon the said sha t is turned until the foot portions of all of thelatcharms C are in enga ement with the rear faces of the other controling-s urs 341and 34, and

at such time a cipher W' l appear at each of' the openings 13. l

To the left of the casing a series'of recording-disks D are looselymounted on the shaft B, and each recording-disk has figures on itsperiphery reading from 0 to 9. On the said shaft B adjacent to the firstrecording-disk a ratchet-wheel D is loosely mounted, provided wth alatch-arm D2, and each of the recordin disks is likewise rovided with alatch-arm 2, all of said latc -arms Dz being alike in 4construction tothe construction of the latch-arms C', heretofore mentioned. Theratchet-wheel D is operated through the medium of a dog 47,corresponding l'to the dog 41 for the registering-disks C, and this dog47 is mounted upon an eccentric 48 at` the inner end of the line-shaft38, as is shown in Fig. 2, the eccentric 48 being a duplicate of theeccentric 39. Each recording-disk D is (provided with a series ofopenings 49 in its si e, correspondin to the openings 27 in theregistering-disks A recording-disk D is located below each o ening ofthe series 13 in the plate 12, so that the figures on said disks may beread at said openlngs, and the operation of the recording-disks isidentical with the operation of the registering-disks, the foot portionof each spring latch-arm D2 being provided with a controlling-spur 50,carried by the bar 14, as is illustrated in Fig. 2. The disks are spacedone from the other, preferably by means of hubs 51, located at one sideface. The recording disks are ada ted to show the aggregate of milestravele in a number of trips, while the registering-disks are adapted torecord simply the number of miles traveled at each trip. Consequently itis not necessary to provide Athe means shown in connection with theregistring-disks to turn the recording-disks back; but such means may beemployed or other means may be utilized for bringing therecording-disks. to .zero when desired. As shown, it will be observedthat the o erationl of the shaft B to set the registeringisks has 3 01ilifluence whatsoever upon the recording- `Patent- Having thusdescribed my invention, I claim as new and desire-to secure byLetters 1.
